A nurse is instructing a group of clients regarding nutrition. Which of the following is a good source of omega-3 fatty acids that the nurse should include in the teaching?
Fish
Leafy green vegetables
Dietary supplements
Corn oil
The Correct Answer is A
A. Fish, particularly fatty fish such as salmon, mackerel, and sardines, are excellent sources of omega-3 fatty acids, which are beneficial for heart health and reducing inflammation.
B. Leafy green vegetables contain some omega-3 fatty acids, but they are not considered a primary source compared to fish.
C. Dietary supplements can provide omega-3s, but they are not food sources and may not be necessary if individuals can obtain omega-3s from their diet.
D. Corn oil is primarily high in omega-6 fatty acids, which do not provide the same benefits as omega-3s and can lead to an imbalance if consumed in excess.

Correct Answer is D
Explanation
A. Assessing the pedal pulses with a Doppler device is not necessary in this situation; the focus should be on the apical pulse due to the irregularity noted in the radial pulse.
B. Assessing the pedal pulses for a full minute does not address the irregularity of the radial pulse and is not the priority.
C. While assessing the apical pulse is appropriate, using a Doppler device is not required unless there are difficulties in obtaining the pulse normally.
D. Assessing the apical pulse for a full minute is the correct action because it provides a more accurate reflection of the heart's rhythm and rate, especially when there is an irregular radial pulse.
Correct Answer is A
Explanation
A. Requesting a prescription for an oral formulation of the medication is the appropriate action, as sublingual medications are designed to dissolve under the tongue and bypass the gastrointestinal tract, which is not feasible with an NG tube in place.
B. Administering the medication under the client's tongue is incorrect because the NG tube prevents effective absorption through the sublingual route.
C. Dissolving the medication in water and giving it through the NG tube defeats the purpose of sublingual administration and may not provide the desired therapeutic effect.
D. Administering the crushed medication through the NG tube is inappropriate for sublingual medications, as this can alter the medication's pharmacokinetics and effectiveness.
